EXTENSION-DRAWER.

TIGN forming part lof Letterslatent No. 676,596, dated JJ' une 1 8, 1 901.

Application filed January 11,1901, Serial No. 42.853. (No model.) d l To all whom t may concern:

Be it known that I, FRANK X. AMMANN, a citizen of the United States, residing at Union Hill, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Extension-Drawers;

and I do hereby declare the following to be a' full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. v

My invention relates to improvements in supports for drawers when pulled out of their cases.

The object of my improvements is to construct extension-drawers in such a manner that they will move perfectly true when pulled out or shoved in the casing, thus facilitating the opening and closing of the drawers and preventingbinding; also, to adaptthese drawers to be maintained in a horizontal position when pulled outof the casing to the full extent of Ithe drawer-space.

My invention consists in an extensiondrawer adapted to be supported horizontally and guided laterally by means of movable guides and supports arranged to move with the drawer when pulled out or shoved into the case. y

In the accompanying drawings, Figure l represents a plan of my improved extensiondrawer; Fig. 2, a longitudinal section of the same, taken on line .fr of Fig. l; and Fig. 3 is a transverse section taken on line y' y of Fig. 1, showing the drawer extended and supported by the carriage.

Referring to the drawings, A A A A desig nate the case of the frame in which the drawer is fitted and adapted to slide in and out.

B B are strips fixed to the sides of the case, parallel to and slightly above the bottom of the case. These strips serve as guides for the extensiblesupports,hereinafter described, that prevent the said supports from tilting when drawn out of the case or extended to support the drawery G represents a frame of rectangular form that is placed on the bottom of the case, into which it fits easily. This frame takes the place of the fixed frame that is commonly placed in the drawer-case and on which the drawer slides. The side members 'd d of the frame are right angular in cross-section and they are connected together transversely by front piece e and a piece f, that connects or joins'the side members at a point about midway between the front piece e and the rear or inner ends of the side members d d. The horizontal parts of the side members rl d of the frame project under the guide-strips B B and at or near the front rest upon antifric'- tion-rollers g g, let into the frame of the bottom of the case. The sides of the drawer project below the bottom of the drawer and form runners 71. h, and when the drawer is placed in the case these runners rest and slide upon the horizontal parts of the side members d d and between the vertical parts of the side members and the guide-strips B B. At or near the back of the drawer a downwardly-projecting pin D is fastened to the bottom. I

E is the drawer, which is constructed in the usual manner, except that the sides da are extended, say, about three inches beyond the end b for the purpose of forming horns F F.

vThe operationof the invention is as follows:

When the drawer is pushed Wholly within the case, the frame is shoved in with it. Now when it is desired to open the drawer it is pulled out and slides on the side members d d, between the vertical sides of the side members and the guide-strips, which thusv guide its motion and prevent it from losing its parallelism with the sides of the case. The side members and the entire frame remain in the case until pin D comes in contact with trans verse piece f, when the pin bearing against the said piece couples the frame and drawer together, so that the farther movement of the drawer outward causes the frame to move out with it, and thus the side membersd d, which serve both as guides and supports for the drawer, follow the movement of the drawer and the vertical parts of the side members guide the drawer, while the horizontal parts form extended supports, whereby the'drawer is held in a horizontal position by the supports, while the vertical parts serve as lateral guides that hold the drawer true with respect to the sides of the case. When the drawer is entirely outside of the case, the horns F F remain within the same and bearing against the top form a counterbalance,

IOO

'the-frame to slide out with the drawer, and

its movement, and when it` reaches the limit' of its independent movement the side members take ynp and com plete ythe movement re,- l quired to carry the drawer to its extreme ex- F s verse piece connecting the sides of the eartended position.

I claiml. In anextension-drawer the combination with the dlawer and its ease of .extensible ,right-angular slides that form supports and guides forrthe drawer when pulled out, guidestrips y fixed .to/the sides of the case over the horizontal part Lo i the right-angular slides to p revent'the slides from tilting when extended and means by which the drawer is caused toengage the ,slides and draw them ont .tol

holdthedrawer parallel to the sides of the ca Se itlldsupport it horizontallyin its extiended position, lsul)stantially as specified.

iIn an extension-drawer the combination with ythe drawer and its caseof areetangular sliding fra-me the side members of which are rightangular in cr,oss.seotion=the horizontal PMIQS O f .the side members forming the snp. port yon which the runners of the drawer rest o and slidefand the .vertical parts ,forming the lateral guides for said runners-a transverse .f

guide-strips fixed to the sides of the case and` over the horizontal parts .of ,the slide members of the frame that prevent the frame from tilting when extended, substantially as specied. l

3. In an extension-drawer, thecombnation 1 ot the `drawer-ease, a drawer provided with a pin, guide-strips located between the sides and a car-y riage for the drawer consisting of a frame,

having right-angular side members held nnder the `guide-strips, stops for limiting the distance 'the carriage canmove and a transriage, which is engaged by the drawer-pin when the drawer is 4pulled out, substantially as specified.
